@Robpol86 I can't grok how so many more tests in appveyor began failing with this change, and they seem unrelated to what I did. Also don't understand the coverage decrease for files other than sphinx_.py. Assigning to you anyways for merge?

[Levi-Armstrong]

👍 @Lingnik Thank you for the fix. I installed your branch and everything worked as expected.

[FraBle]

@Robpol86, please merge this PR :)

@Robpol86, any updates on this PR?

@Robpol86 mind merging this one? If you don't maintain the repository anymore - please let someone else (e.g. one of the already existing contributors) take over.

to install patched version

pip install -U git+https://github.com/Lingnik/sphinxcontrib-versioning@Lingnik-patch-1

Hi guys, is sphinx-versioning reinstalling/using the package in different commit? It seems that it only uses the master branch version. Therefore, the doc building often fails. Any comments? Thanks!

[sizmailov]

@zhanghang1989, sphinx-versioning checks out different commits, but does not perform install. If you have pure python project that should be enough to build documentation correctly.

In my project I have C++-extension module, so I need install to properly generate module API with autodoc.
I added several options to sphinx-versioning to actually trigger python setup.py install during doc generation, try the fork (it includes Lingnik's patch):

pip install -U git+https://github.com/sizmailov/sphinxcontrib-versioning@conditionally_run_setup_py

This change seems to remove entirely the default sidebars for me - I just end up with the versions in the side bar, but when building standalone I get a TOC and a few others.
